I can't say enough good things about this product!
My young Persian is not sneezing anymore, nor does she has a runny nose or a troublesome ear!
She had these issues since she was 4 months and now she almost 1 year old. We give her 750mg a day (2 chews in the morning and 1 at night) and has been doing this for about 1.5 months, she got rid of her problems after just 1.5 weeks.
She loves the taste of them and comes running when we shake the bag! :)

good amount of lysine for my kitty, one a day makes him more active with the combination of daily best/hairball supplements.
he loves the taste and smell of the chew, came running once he hears me opening up the packet, unless hes full. but even when full, he doesnt mind eating the chew if i put it infront of his face. other than that, down side would be one chew is rather big, so i have to break it into 4-5 smaller pieces so that he can swallow it down, but no problem with that, because it tricks him into thinking that i gave him many treats and he would stop asking for more after. :)

The L-Lysine certainly helped my kitty--her eyes do not have as much discharge and she doesn't squint as much. I put the chew on top on her food. It is not a crunchy chew so she won't eat it like a treat. I may try crunchy ones next time I order if they have them.
